Changing individual portfolio pages. HUGE PROBLEM

Question:
HOw do you make sure the portfolio app creates individually different pages. Everty time I edit an individual project paje and publish it, it changes for all the other pages. I have realised that even when I view my site and press publish, that some poeple in the help desk see updated changes, but for me it glitches… any advise?

What are you trying to achieve:
I want to create portfolio pages that have unique content.

What have you already tried:
I have been creating what I think are unique pages, but are not in fact unique pages. the information keeps changing across the entire template portfolio. I am afraid I lost my previous work on other pages.

Additional information:
I am using a site that has a portfolio within the site.
